I want to express my disappointment at the lack of urgency shown by BMW in addressing my concerns with regards to the recall issued due to malfunctioning of the front air bag seat occupancy sensor mat. My car had this problem in mid dec 2013, just before the recall notice was issued. Since this malfunction was safety related, I rushed to get the car repaired immediately. My local BMW dealer did not have the sensor module available; therefore, I had to get the repair done from the certified BMW service professional where I incurred an expense of $851.84. I have been following up with BMW since January to get paid for this repair and have made repeated calls (on dates 3/26, 4/15, 6/9) but every time I get told that I have to wait to get this payment. Unfortunately, I have run out of patience. How can you make your loyal customers go through this disgraceful ?run around?? …

Started the engine. Passenger sat in vehicle. The passenger restraint system failure light appeared on screen. I thought it was a glitch. The light appeared on and off for several weeks. Went to an independent mechanic and told that it was the seat mat or sensor and the cost would run around 1500 at the dealer. Was told to check to see if there was a recall. Checked on the website and there was no recall but many complaints about the same problem occurring for the 2006 vehicles.
